摘要： In a solar system collector loop, having a solar collector with an absorber plate, a heat storage unit and a pump for circulating a fluid between the collector and the storage unit, the stagnation temperature T.sub.Q of the collector absorber plate, the temperature T.sub.C of the collector absorber plate, and the storage temperature T.sub.S in the storage unit are measured. The stagnation temperature is measured by a heat flux transducer based on a small sample of the absorbed plate which is thermally isolated from the collector but in the same enclosure. This transducer generates temperatures near the stagnation condition for the instantaneous operating point. In the method of control, the pump is turned on when the temperature difference between the absorber plate T.sub.C or T.sub.Q and the storage T.sub.S, is greater than a predetermined value T.sub.on. The pump is turned off when the temperature difference between the stagnation temperature T.sub.Q and collector absorber plate T.sub.C is smaller than a predetermined value T.sub.off. The temperature signals T.sub.Q, T.sub.C and T.sub.S may also be used to control obvious abnormalities in the system as well as fast radiation changes such as those caused by small clouds.

摘要： The timed AC switch comprises a manual on-off switch in series with bidirectional semiconductor switch, such as a triac, for connection in a loop with an AC source and a load which would generally be incandescent or fluorescent lamps. The semiconductor switch is driven by an RC oscillator which is under the control of an inhibit circuit and a digital counter which itself is driven by the oscillator. The counter is reset at initial start up, and may also be reset while operating or after counting out. The times switch may also be controlled to inhibit the oscillator for a very short time as a warning before finally timing out.

摘要： A magnetic bubble propagation circuit consisting of magnetic material bars positioned over the bubble supporting material to define the bubble propagation path. Each bar is spaced from the bubble material such that a uniform gradient is formed between the bar and the bubble material in the direction of the propagation path. A periodic pulsed or sinusiodal magnetic field of sufficient strength to magnetize the bars is applied in the plane of the material and parallel to the propagation path to cause a bubble to move from one bar to an adjacent bar, and the gradient causes the bubble to move from one end of the bar to the other when the field is removed.

摘要： An optical system for angle measurement by interferometry comprises four retroreflectors arranged in pairs as beam pathlength multipliers, with two adjacent ones of the retroreflectors rigidly mounted and the other adjacent ones mounted for rotation together about a common axis. A beam of electromagnetic energy, for example a laser beam, is directed towards a beam splitter by which means it is split into two secondary beams, one secondary beam being directed to pass back and forth between one pair of the retroreflectors while the other secondary beam is similarly directed by a beam folder to pass back and forth between the other pair of retroreflectors. Both reflected beams are redirected by retroreflectors along similar paths between their respective retroreflectors to the beam splitter where interference between the secondary beams occurs. The angular displacement of the movable retroreflectors is deduced from the distance between their ridges and the number of fringes generated at the beam splitter.

摘要： The sensing of magnetic bubble-domains is presently carried out using one of four techniques: inductive, magnetooptic, galvanomagnetic and magnetoresistive sensing. These techniques have a number of drawbacks such as size, complexity or inadequate sensitivity. The present invention provides for the sensing of bubble domains by first converting the energy associated with the bubble magnetic field to mechanical energy, and secondly by converting the mechanical energy to electrical energy which provides an electrical signal indicating the presence of a bubble domain. This method is carried out in a sensing device having a layer of magnetostrictive material in which the magnetic field produces an elastic strain and a layer of piezoelectric material which is fixed to the magnetostrictive material and converts the mechanical energy to electrical energy.

摘要： Salts such as calcium and sodium chlorides are co-pelletized into composite pellets by contacting larger nuclei with finer particles in the presence of a salt solution which is substantially saturated in the salt of finer particle size and at least partially saturated in the other salt (or salts). This liquid acts as a viscous binder and binds the salts together into pellets in which the finer particles tend to be layered around the coarser nuclei. If desired, migration of part of the coarse nuclei salt toward the surface can be achieved. The pellets are easily handled without dusting and are useful e.g. for ice melting and dust control on roads.

摘要： Articles of polymers susceptible to degradative attack by ultraviolet radiation are stabilised by the application of a very thin continuous layer of an energy transfer agent which does not significantly absorb radiation in the ultraviolet region of the spectrum. The energy transfer agent should be a metal coordination compound containing a metal atom, and a ligand either having as electron donor atom or atoms, one or more nitrogen, oxygen or sulfur atoms, or comprising a cyclic olefin; or a substituted phenol, and the agent is used in amounts of at most 0.5% by weight based on the weight of the polymeric substrate. The stabilised articles demonstrate prolonged resistance to ultraviolet degradation.
